SCHNEIDER AS-BDAU-208
AS-BDAU-208 is an analog output module in the Schneider Electric Modicon series. It is commonly used for I/O expansion in TSX Compact series PLCs (Programmable Logic Controllers).
Below are the main technical parameters and application details of the AS-BDAU-208:
1. Core Functions and Features
- Analog Output:
This module provides analog output functionality and is commonly used to drive valves, variable frequency drives (VFDs), or transmit analog signals to supervisory systems. - Number of Channels:
The standard configuration typically includes 2 channels, with each channel supporting 0–10 V or 4–20 mA output modes. - Compatibility:
Specifically designed for the TSX Compact (Modicon 18130) series, allowing direct installation into the I/O rack (slot).
2. Detailed Technical Specifications
According to publicly available product catalogs and technical documentation (including official Schneider Electric materials), the main technical specifications of the AS-BDAU-208 are as follows:
| Parameter | Description |
|---|---|
| Model | AS-BDAU-208 |
| Type | Analog Output Module |
| Channels | 2 channels |
| Output Range | 0–10 V DC or 4–20 mA |
| Accuracy | Typically ±0.5% (depending on the application environment) |
| Supply Voltage | 24 V DC (for module power supply) |
| Compatible PLC Series | Schneider Modicon TSX Compact (e.g., 18130-A series) |
| Mounting Method | DIN rail mounted, inserted into I/O rack (slot) |
| Protection Rating | IP20 (internal module) |
3. Typical Application Scenarios
The AS-BDAU-208 is commonly used in the following applications:
- Process Control:
Sending speed reference signals to variable frequency drives or position commands to proportional valves. - Instrument Display:
Outputting voltage signals to drive field instruments such as pressure gauges and temperature indicators. - Signal Simulation:
Simulating real process signals for laboratory or testing environments.
